First edit the program from your source library.
come out of the editor
Logon to the destination library
simply ehter the E command in the command line in main menu
This should again open the same program in edit mode.
now save/stow the program... this will create the copy in your desired lib.
Above is possible if you have the access to the source lib. Some times if the source is Production lib, you may not be able to do it.
